are they a viable source of onboarding normal people into cryptocurrencies?
There's a huge possibility that it will attract more people to get in to cryptocurrency especially if most of them heard many good news from bitcoin.
Most of the time I suggest my friend's to invest in cryptocurrency but they are too busy to listen on my explanations and didnt focus on me.
Yeah that's a problem with blockchain in general. It's difficult to explain it shortly enough for people to keep their interest, without losing all the small points that shows exactly why we are so obsessed with it.
